Our previous studies highlighted the involvement in the progression of different types of cancer of four lncRNAs: Metallophosphoesterase Domain-Containing 2 Antisense RNA 1 (MPPED2-AS1), Rhabdomyosarcoma-2 Associated Transcript (RMST), Kelch-like protein 14 antisense (Klhl14-AS) and Prader Willi/Angelman region RNA 5 (PAR5) [14,15,16,17]. Here, MPPED2 is linked to cancer.
